Additionally, thecontact system 10 can have a printed circuit board 25 (indicated by a dashed line inFIG. 1 ). Thefirst contact device 15 has afirst contact housing 30. Thefirst contact housing 30 has on its underside at least onepin 35, fourpins 35 in the shown embodiment, which are arranged spaced apart from one another in a square. Thepins 35 engage in corresponding pin receptacles of the printedcircuit board 25, and secure thefirst contact housing 30 to the printedcircuit board 25. Thepin 35 can be electrically connected to a first conductor path of the printedcircuit board 25. Thefirst contact housing 30 is configured in an electrically conductive manner and has at least one of the following substances: zinc, tin, aluminum, copper, magnesium, brass, iron, steel, bronze, zinc casting, zinc alloy, ZnAlCuMg. In an embodiment, thefirst contact housing 30 is cast, in particular in a pressure die-casting. - The
first contact device 15 and thesecond contact device 20 are connected to one another, as shown inFIG. 1 . Thesecond contact device 20 has asecond contact housing 40, saidsecond contact housing 40 being plugged onto thefirst contact housing 30. Thesecond contact housing 40 can have an electrically conductive or an electrically insulating substance. The substance of thesecond contact housing 40 can be identical to the substance of thefirst contact housing 30. -
FIG. 2 shows a sectional view along a section plane A-A, shown inFIG. 1 , through thecontact system 10 shown inFIG. 1 . Thefirst contact device 15 has, in addition to thefirst contact housing 30, a firstcoaxial contact unit 45. Thesecond contact device 20 has a second coaxial contact unit 50 (depicted schematically in dashed lines inFIG. 2 ). The secondcoaxial contact unit 50 is configured in a manner corresponding to the firstcoaxial contact unit 45 and is thus configured as a femalecoaxial contact unit 50 in the embodiment. It would also be conceivable for the firstcoaxial contact unit 45 to be configured as a femalecoaxial contact unit 45, and for the secondcoaxial contact unit 50 to be configured as a malecoaxial contact unit 50. - As shown in
FIG. 2 , the firstcoaxial contact unit 45 has a firstouter contact 55, aninsulating element 56, and a firstinner contact 60. The firstinner contact 60 and the firstouter contact 55 are guided in sections coaxially to acontact axis 65. Thecontact axis 65 extends parallel to the x-axis. Theinsulating element 56 is arranged, radially in relation to thecontact axis 65, between the firstouter contact 55 and the firstinner contact 60. The firstouter contact 60 is configured cylindrically on the inside in the shown embodiment. Theinsulating element 56 has a dielectric as the substance. Theinsulating element 56 electrically insulates the firstinner contact 60 from the firstouter contact 55. - The second

inner contact 60 is configured as an angular plug and, as shown inFIG. 2 , has an angledangular section 80 and afirst contact section 85. Theangular section 80 is arranged inclined, perpendicularly in an embodiment, to thecontact axis 65 and to thefirst contact section 85 and runs in the z-direction. Thefirst contact section 85 is electrically connected to the secondinner contact 75. Theangular section 80 is aligned parallel to thepin 35. On the underside, theangular section 80 engages, with asecond contact section 90, in the printedcircuit board 25 and electrically connects theangular section 80 to a second conductor path of the printedcircuit board 25. - As shown in
FIG. 2 , thefirst contact housing 30 has afirst encoding unit 95 and afirst housing section 100. Thefirst housing section 100 is configured in a substantially cuboid manner and has afirst contact receptacle 105 for receiving the firstcoaxial contact unit 45. In the embodiment, thefirst contact receptacle 105 is arranged substantially in a central location in relation to the configuration of thefirst housing section 100. - The
first encoding unit 95 is arranged at afirst end face 110 of thefirst housing section 100, as shown inFIG. 2 . Thefirst end face 110 extends in a yz-plane and is configured in a planar manner. Thefirst encoding unit 95 and thefirst housing section 100 are configured in an integral and materially uniform manner. In this case, thefirst encoding unit 95 protrudes over thefirst end face 110 in the direction of thesecond contact device 20. - As shown in
FIG. 2 , thesecond contact housing 40 has asecond housing section 115 and athird housing section 120. On the inside of thesecond housing section 115 there is provided asecond contact receptacle 125 for receiving the secondcoaxial contact unit 50. Thesecond housing section 115 is arranged on a side facing away from thefirst housing section 100. Thethird housing section 120 of thesecond contact housing 40 is arranged between thefirst housing section 100 and thesecond housing section 115. In the y-direction and z-direction, thethird housing section 120 is configured slimmer than thesecond housing section 115. Thesecond contact housing 40 has afirst receptacle 130. Thefirst receptacle 130 is configured as a through-hole in thethird housing section 120 and formed in aside wall 136 of thesecond section 115. Thefirst receptacle 130 opens onto a side, facing away from thefirst contact device 15, in thesecond contact receptacle 125. In this case, thefirst receptacle 130 is configured slimmer in the z-direction thansecond contact receptacle 125. -
FIG. 3 shows a cutout of the sectional view, shown inFIG. 2 , along the section plane A-A, shown inFIG. 1 , through thecontact system 10. Thefirst receptacle 130 has afirst section 135 and asecond section 140. Thefirst section 135 and thesecond section 140 are arranged in theside wall 136, which extends in a yz-plane, of thesecond housing section 115. Thethird housing section 120 is connected by one side to theside wall 136. Thefirst section 135 of thefirst receptacle 130 is configured running parallel to the x-axis and has a constant cross-section. Thefirst section 135 can also be configured conically and tapering from thefirst end face 110 in the direction of thesecond housing section 115. Thesecond section 140 adjoins thefirst section 135 in the x-direction and is arranged on a side of thefirst receptacle 130 facing away from thefirst end face 110. Thesecond section 140 widens from thefirst section 135 in the direction of thesecond housing section 115. Thesecond section 140 opens into thesecond contact receptacle 125. - The
first encoding unit 95 has a firstriveting device 141 with afirst shaft section 145 and afirst head section 150, as shown inFIG. 3 . Thefirst shaft section 145 is connected to thefirst housing section 100 at a firstsolid end 155. Thefirst head section 150 is arranged at a firstfree end 160 of thefirst shaft section 145. Thefirst shaft section 145 engages in thefirst section 135. Thefirst shaft section 145 is configured circumferentially corresponding to thefirst section 135 and positions thefirst contact housing 30 relative to thesecond contact housing 40. In the embodiment, thefirst shaft section 145 is configured like a hollow body. The firstouter contact 55 is arranged on the inside of thefirst shaft section 145. At the end face, the firstouter contact 55 protrudes over thefirst head section 150. The insulatingelement 56 ends approximately at the level of thefirst head section 150. - In the embodiment shown in
FIG. 3 , the firstouter contact 55 and thefirst encoding unit 95, in particular thefirst shaft section 145, are configured in an integral and materially uniform manner. It would also be conceivable for the firstouter contact 55 and thefirst encoding unit 95, in particular thefirst shaft section 145, to be configured in several parts. As a result of the electrically conductive substance of thefirst contact housing 30, reliable shielding of the firstinner contact 55 against electromagnetic interference is also ensured in the case of an integral and materially uniform configuration of thefirst encoding unit 95 with the firstouter contact 55. The integral and materially uniform configuration of the firstouter contact 55 together with thefirst encoding unit 95 furthermore has the advantage that an electrical resistance to the attachment of the firstouter contact 55 to the first conductor path of the printedcircuit board 25 is particularly low. - The
first head section 150 engages in thesecond section 140 as shown inFIG. 3 . In this case, thefirst head section 150 lies with a firstcircumferential side 175 against the inside of thesecond section 140. Furthermore, thefirst head section 150 protrudes in the z-direction and y-direction with the first outercircumferential side 175 over a second outer circumferential side of thesecond section 140. In addition, thefirst head section 150 can lie against aninner side 170 of thesecond contact receptacle 125, on a side facing away from thefirst end face 110. Thefirst head section 150 thus engages behind thesecond contact housing 40, in particular theside wall 136, such that thefirst contact housing 30 is connected in a form-fitting manner to thesecond contact housing 40. On the rear side, thethird housing section 120 can lie against thefirst end face 110 at the end face or thefirst shaft section 145 can widen at thesolid end 155, such that thefirst receptacle 130 comes to a stop on a widenedportion 176 and agap 177 is provided between thefirst end face 110 and asecond end face 250 of thethird housing section 120. As a result, a particularly secure hold of thefirst contact housing 30 on thesecond contact housing 40 is ensured by the firstriveting device 141. The form-fitting connection can only be undone by destroying theriveting device 141. As a result, an unintentional pulling-away of thecontact housings - A

first shaft section 145, as shown inFIG. 4 , has afirst region 190 and asecond region 195. Thefirst region 190 is configured longer than thesecond region 195 in the x-direction. Furthermore, in the y-direction and in the z-direction, thesecond region 195 is configured slimmer than thefirst region 190. - The
first region 190 borders the firstsolid end 155 and adjoins thefirst end face 110 of thefirst housing section 100, as shown inFIG. 4 .

In the embodiment, thefirst guide surface 200 is configured as an xy-plane. Thefirst guide surface 200 is aligned parallel to thecontact axis 65. - In the z-direction lying opposite, the
first shaft section 145 furthermore has, at the second outercircumferential side 180, a second guide surface 205 (arranged on a side of thefirst shaft section 145 facing away from the viewer inFIG. 4 ). Thefirst guide surface 200 and thesecond guide surface 205 are each configured in a planar manner and are arranged in xy-planes arranged parallel to one another. Thefirst guide surface 200 and thesecond guide surface 205 are furthermore aligned parallel to anunderside 210 of thefirst housing section 100.
